COMBINATIONr-LOCK FOR A UTOMOBllL ES.

Be it known that I, ARTHUR HERBERT BUoKLnY, a citizen of Australia, and a"resi-' dent of Paddington, Sydney, New South Wales, Australia, have invented a new and useful Improvement in Combination-Locks for Automobiles, of which the following is a full, clear, and exact description. 3 My invention relates to improvements in combination locks for automobiles, and it consists in the combinations, constructions and arrangements herein described and claimed. I n

An object of my invention is to provide a 'device by means of which an auxiliary valve in the fuel feed line. of an automobile-engine may be locked in position so as to shut off the flow of fuel, and thereby prevent theoperation of the engine, thus circumventing any attempt to steal the car by running it off on its own power.. I a

A further object of my invention istoprovide a device of the type described'in which the movementof a single lever in one direction will instantly bring the auxiliary valve into its closed and locked position.

A further object of my invention is to provide a novel form of combination lock provide a combination lock in which the which is comparatively simple in operation. A further object of my invention is to combination may be rapidly changed without dismantling the apparatus.

Other objects and advantages W111 appear in thefollowing specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accompanying drawings, forming part of this application, in 'which.

In carrying out my"invention-,"I provide a fixture 1 which consists of a cylindrical'eonnection between the carbureter 2 (see Fig.

7 2) and the pipe 3 leading to the intake manifold (not shown). This-connection 1 is a valve 1 of the butterfly type, this valve being secured to a stem 5' which is carried within a tubing or housing 6.1 secured to the stem 5 isan operating rod 7 Whenthe rod 7; isturnedfit' will open onclose the valve, depending upon the amount of rotation. .In Fig. 1, the valve is shown open and when the rod is rotate'dv at 90 the valve 7.

is closed; V a a a 7 *Referring now;particularly to Fig. 5', it

. will be seen that the opposite endof the rod be secured to the dash-board 1601: an automobile. The plate 15"has a'recess 17, in

ice

which is disposed a retaining plate 18 for a [movable disk 19, having a flange 20 arranged to overlie the outer edge of the disk 9. The

' plate 18*is provided with a flange 21 for holding the disk 19 in position while per-- mitting rotation of the latter. plate 22 is mounted on the extension 13, this plate being provided with three slots 23, 24 q and 25 (see Fig.8),the slots 23 and25 hav- A circular ing enlarged end portions, as shown. The

- plate 22 is ,held in fixed relation with an exterior ring 26 by means of a small screw 27. The ring 26 is provided with bosses 28-wh1ch are provided'with' openings arranged to receive rods 29 which pass through the bosses and through" registering openings in the disk 15, being provided with nuts, 29 for sei curing the rods in position. The opposite ends of the rods 29 are secured to an end plate 30 to constitute the end plate and guide cage forithe movable'elements of the locking mechanism, as will be explained later. 'Within the ring 26 is a fixed sleeve 31 i having a shoulder 32. 25 are the three nested sleeves 32, 33 and 34 re- Disposed at one end of the extension 13 spectively. It: will be observed that the sleeve 32 is mounted directly on the shaft for slidable movement with respect thereto. Itihas a central recess 35 by means of which i a cap 36 may be screwed onto the end of the extension 13 to engage a'shoulder'37 -on the sleeve 32 to limit the movement of the latter. The sleeve 33 is rotatable with respect to the sleeve 32, but is held in enga ement therei with by a nut 38 on the threaded end ofthe sleeve 32. A nut 39 on the threaded end of the sleeve'33 retains the sleeve 34 in engage- -ment with the sleeve 33. A spiral spring 40'isdisposed between the end ofthe sleeve .32 and the disk 22 to normally keep the nested sleeves extended toward the left in Fi 5. i

* sfwillbe seenfrom Figs. 5 and 12, the sleeves are provided with peripheral recesses 41' which are spacedat equal distances and V which; may be brought into alinement for a purpose hereinafter explained. a

Y Mounted on each sleeve for f rotation thereon s a r1ng,-these rings being shown at 42, 43 and44 respectively. Each. ring is provided with. a, series of numerals on a beveled portion thereof, these numeralscorresponding to the notches 41. Each ring is "provided with an inwardly extending pin. Y 45 which-is arranged to enter one ofthe recesses of its asso iated.sleeve. v

As will be observedfrom Fig. 5, the sleeve 34-is provided with a pin 46 havinga'groove 47 nearone end. Thenut 39 is provided with a plin48having a groove 49 near one fe'nut 38is' provided with a pin 50. Thepins 46, 48 and 5,0'are designed to enter the openings 25,23 and-'24 respectively in the :plate 22 under conditions to be explained later. It will be noted that in Fig.

5, these pins are all shown on one side of the center of the extension 13, but this position is one of many positions in which the sleeves are locked out from being moved forward because of the fact that the pins are not in positionto enter the slots. Referring now particularly to F 1g. 7, 1t

will be noted that the disk .9 is provided with three openings 9*, 9 and 9 which are arranged to register with the ends of the slots 23, 24 and 25 in the disk 22, so as to permit the entrance of the pins when such registration takes place, and when the pins are in the proper position, as determined by the relative position of the sleeves. It will also be noted that in Fig. 5, while the disk 9 is rotatable, together with the rod 7 to which it is secured, the disk 22 is in fixed relation with the dash-board. The slots 23, 24 and 25 will permit the rotation of the disk 9 with respect to the disk 22, while preventing the retraction of the pins until they reach the enlarged ends of the slots. 3 Secured to the disk 19 (see Fig. 6) is a thereof may be readily understood. In the normal operation of the car, that is to say, when the lock is not desired to be used, the rings 42, 43 and 44, as well as the sleeves 32, 33 and 34, are moved rearwardly into the position shown in Figs. 1 and 5. 'It has been before stated that in order to push the rings and the sleeves forwardly, the slots 41 (see Figs. 1 and 3) must be in registration. Not only this, but the right combination must be secured before the forward movement can take place. Assume that'the combination is 9-5-1 (see Fig. 4), the rings are turned until they are in the position shown in Fig. 4, in which position they register with the indicating mark 99. r The rings,

together with their sleeves, may now be pushed forward and the pins 46, 48 and 50 will enter their-respective slots 25, 23"and 24 in the plate 22. 1 v

fly valve 4 is locked in the-position so that no gas can pass from the carbureter 2 into the engine. The procedure for unlocking the valve is as follows:

The rings 42, 43 and 44, and the sleeves 32, 33 and 34 of the lock are in the back position, resting against'the. plate To open the butterfly valve, the rings 42, 43 and ['44 mustb'e arranged so that certain num- Let usassume thatthe auxilia'rybutter- I 51 is used. The procedure for locking the.

bers thereon are in alinement, which will place the sleeves 32, 33 and 34in position so that the pins 46, 48 and 5,0,which aresecured to the rings 34, 33 and 32, are in alinement withone end of the slots 25, 23 and 24 of the plate 22.. The rings 42, 43 and 44, together withthe sleeves 32, 33 and 34, areipushed forward and'turned to the left, the ends of,

the pins 46, 48 and 50 passing through the slots 25, 23 and" 24 and into the holes/9,

9, and 9 of theldisk 9, to which-is secured the rod 7 which. is fastened to the butterfly i valve4. When the rings 42,43 and 44 are turnedto the left, after they have been arranged in alinement and' pushed forward so that the ends of the pins 46, '48 Land 50 are in the holes 9, 9*; and-9 of the; disk 9,

rings 42, 43 and '44 and the sleeves 32, 33 V and 34 will be in the back position again. The butterfly valve 4 is then open as far as it can be. The butterfly valve 4 may be locked bymeans of the rings or the lever 51. The

procedure for locking the valve by means of the rings is the same as opening it, except the direction of rotation is reversed. The rings, after being arranged in alinement, are pushed forward, then turned to the right, until they are pushed out by the spring 40. The butterfly valve 4 is then closed.

For instantly locking the valve 4, the lever valve 4 by means of the lever 51 is described as follows: When the butterfly valve 4 is open and the rings and the sleeves are in the back position, the lever 51, which is integral with the disk 19, is in the dotted position, as shown in Fig. 6; The butterfly valve 4 is instantly closed by simply moving the lever 51 into the position shown in full lines in Fig. 6. The flange 20 of the disk 19 engages the shoulder 52 of the disk 7 9 and rotates the disk 9 until it is stopped by the shoulder 53 engaging with the pin 54.

When opening the valve 4, the shoulder 52 of the disk 9 engages the flange 20 of the disk 19, of which the lever 51 is integral, and rotates it until the flange 20 engages the pin 54.

For safety purposes, the combination of the lock may be changed by changing the rings with relation to the sleeves. The rings 42, 43 and 44 are changed by placing the lock in the position shown in Fig. 10, and pushing all the rings against the plate 30 while the sleeves 32, 33 and 34 are in the forward position. This allows the rings to r0- tate around the sleeves32, 33 and 34, the pins 45 of the rings rotating in the recesses 101 of the sleeves. It will be noted that in 7 order to change the combination, one must know the previous combination which. is

necessary for unlocking the device- It is, 3

therefore, apparent that unauthorized persons mayznot change the combination, since they will not know the previous combination, and hencecannot change the 'combination in the absence of the owner and to his detriment: 1
